2001 BUICK REGAL key battery

1-29

Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the frontal air bag system. The module records
information about the readiness of the system, when
the system commands air bag inflation and driver's
safety belt usage at deployment. The module also
records speed, engine rpm, brake and throttle data.

Let only qualified technicians work on your air bag
systems. Improper service can mean that an air bag
system won't work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver's or the
right front passenger's air bag, or the air bag
covering on the driver's seatback, the bag may not
work properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or the air bag module
and seatback for the driver's side impact air bag.
Do not open or break the air bag coverings.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag systems. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag systems do not need regular maintenance.

Delayed Locking
Delayed locking allows a brief time period for you to
re
-enter the vehicle after the doors have been closed and
locked. Delayed locking is user programmable for
enabling or disabling the feature.
Delayed locking is activated when a door lock switch is
pressed while the key is not in the vehicle's ignition, and
a door is open. The door lock switch may be either the
lock switch on the door or on the remote keyless entry
transmitter (see ªRemote Keyless Entryº earlier in this
section for more details). The doors do not lock when
the lock switch is pressed, but instead, three chimes are
heard. These chimes indicate that the delayed locking
function has been activated.

the locking of the vehicle, no additional action is
required. The delayed locking feature will lock the doors
automatically after all the doors have been closed for a
period of five seconds. During this five second period,
any door may be reopened, at which time the three
possible actions shown above are again available.
You may also customize your vehicle to activate the
delayed locking feature as described previously, or you
may choose to completely disable the feature at all
times. If disabled, the power door locks will activate
immediately when a power door lock switch is pressed.The enabled/disabled state of the delayed locking

2-16 Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
To replace the battery:
1. Insert a flat object like a dime into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Remove the old battery and replace it with the new
one. (Use type CR2032 or an equivalent.) Make sure
the positive (+) side of the battery is facing down.
Do not use a metal object to remove the old battery.
3. Snap the top and bottom together, making sure the
halves are together tightly so water won't get in.
4. Test the operation of the transmitter with your vehicle.

1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start within 10 seconds, hold your key in
START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between each try.3. If your engine still won't start (or starts but then stops),
it could be flooded with too much gasoline. Try
pushing your accelerator pedal all the way to the floor
and holding it there as you hold the key in START
for about three seconds. If the vehicle starts briefly
but then stops again, do the same thing. This time
keep the pedal down for five or six seconds to clear the
extra gasoline from the engine. After waiting about
15 seconds, repeat the normal starting procedure.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.

2-34 Shift Lock Release
Your vehicle is equipped with an electric park lock
system. The system is designed to prevent ignition key
removal unless the shift lever is in PARK (P) (with the
shift lever button fully released).
The system also prevents the shift lever from moving
out of PARK (P) when the ignition is in OFF or in
LOCK. The park lock system is always functional
except in the case of a dead or low voltage
(less than 9 V) battery.
If your vehicle has a dead battery or a battery with low
voltage, there are two override access slots that will
allow you to override the park lock system.
The first access slot is located underneath the steering
column below the lock cylinder. To use this slot,
do the following:
1. Verify that the shift lever is in PARK (P)
(with the shift lever button released.)
2. Remove the override access slot cap, which will then
show the override mechanism release button.
3. Insert a key or screwdriver into the access slot and
then press in and hold the override mechanism
release button.
4. Turn the ignition key to OFF.5. Remove the key from the ignition switch.
6. Put the override access slot cap back on.
You will not be able to remove your key from the
ignition unless the shift lever is in PARK (P) with the
shift lever button fully released.
The second override
access slot is located
on the upper right side
of the shift panel. To use
this slot, do the following:
1. Remove the override access slot cap.
2. Insert a key or screwdriver into the access slot, press
in and hold the override mechanism release button.
3. Pull the shift lever into the desired gear position.
4. Reinstall the override access slot cap back on.
